Staying in Cascais is absolutely worth it, especially if you want a sophisticated blend of coastal beauty, historic charm, and proximity to Lisbon. Located just 30 minutes by train from the Portuguese capital, Cascais offers a much more relaxed, "resort" feel than the bustling city. It features beautiful sandy beaches like Praia da Rainha, world-class seafood restaurants, and the dramatic "Boca do Inferno" (Hell’s Mouth) cliffs. The town is highly walkable, with a charming "Old Town" filled with boutiques and cafes. It also serves as an excellent base for exploring the fairytale palaces of Sintra or the rugged surfing beaches of Guincho. While hotels in Cascais can be more expensive than those in central Lisbon, the quality of life—marked by fresh sea air, scenic coastal walks, and a safe, upscale environment—provides excellent value. It is the perfect choice for travelers who want to spend their mornings sightseeing in the city and their afternoons lounging by the Atlantic Ocean, enjoying the "Portuguese Riviera" lifestyle that has attracted royalty and celebrities for over a century.
